Case Study — FINancial Services· Mortgage LENDING
Up to 60 X Faster API
Regression with AI-Driven
QA Automation
We partnered with a leading retail mortgage lender to transform their manual QA processes into an AI-driven automation framework. By introducing intelligent test generation, dynamic change detection, and unified API/UI automation, we reduced regression time from hours to minutes, expanded coverage, and enabled real-time stability tracking across releases.

Key Details
Industry: Financial Services → Mortgage lending Geographies: United States
Platform: BrowserStack, GitHub
Business Challenge
The client’s QA process relied heavily on manual testing, limiting release velocity, coverage, and system stability visibility.
Lack of a standardized API/UI automation solution led to inconsistent validation and duplication of effort.
Testing cycles consumed significant QA bandwidth, delaying feedback and slowing releases.
Absence of automated health checks made it difficult to track API and UI reliability across builds.
Our Solution Approach
We implemented an AI-first automation framework to unify API and UI testing, reduce manual effort, and enable continuous validation.
1 · Discover
Identify QA Bottlenecks & Coverage Gaps
Analyzed regression workflows, endpoint coverage, and UI testing inefficiencies to define automation opportunities.
2 · Consolidate
Build Unified API & UI Automation Framework
Established a single framework supporting API validation, schema checks, UI testing, and reporting.
3 · Automate
Enable AI-Driven Test Generation
Leveraged AI to generate test cases from Swagger, detect schema changes, and auto-create scalable UI test structures.
4 · Deploy
Integrate Continuous Testing into CI/CD
Enabled automated test execution with parallel runs, real-time reporting, and proactive stability monitoring.
Technical Highlights
AI-generated test cases from OpenAPI/Swagger specs with automated schema validation Dynamic test regeneration engine for API contract changes without manual intervention Playwright-based execution framework for parallel API and UI testing AI-assisted test scaffolding using GitHub Copilot with Page Object Model (POM) architecture Cross-browser execution via BrowserStack for distributed UI validation Automated reporting with Allure dashboards for test insights and failure analysis

Business Outcomes
Transformed manual QA into an AI-driven continuous testing system with measurable gains in speed, scale, and product quality.
60X
Reduced execution time from 4–12 hours to under 2 minutes, while increasing endpoint coverage.
100%
Moved from manual, infrequent testing to fully automated daily regression cycles.
2X
Expanded validation across API and UI layers while identifying defects earlier in the development cycle.
